DO-recorder with LoRaWAN®
The DO-IoT compact measuring system uses LoRaWAN® technology (Long Range Area Network) and can therefore transmit data to the gateway at close range without using a mobile phone provider. From here, the data can be transmitted to the server via Ethernet or 2/3/4 G technology. The LoRaWAN® technology is extremely energy efficient; a battery life of up to several years can be achieved. An additional advantage is that the signal easily transmits through buildings and is able to transfer data from under-floor measuring points. This technology is ideal for building up your own networks.
